Retaining walls must be designed so that foundation pressures do not exceed allowable bearing pressures, wall settlements are tolerable, safety factors against sliding and overturning are adequate, and the wall possesses adequate structural strength. Methods for evaluating earth pressures on retaining walls and design procedures are summarized herein for cohesionless backfill materials, which should be used whenever practicable. Course Outline 1. DESIGN CONSIDERATIONS FOR RETAINING WALLS 2. EARTH PRESSURES 3. EQUIVALENT FLUID PRESSURES 4. DESIGN PROCEDURES FOR RETAINING WALLS 5. CRIB WALL 6. EXCAVATION SUPPORT SYSTEMS 7. STRUTTED EXCAVATIONS 8. STABILITY OF BOTTOM OF EXCAVATION 9. ANCHORED WALLS This course will give you an introduction to the design and construction issues for excavation support structures and retaining walls.
